Solder resisting plug hole air guiding plate and manufacturing method therefor

Abstract

The invention belongs to a production auxiliary tool of an electronic product, and specifically relates to a solder resisting plug hole air guiding plate and a manufacturing method therefor. A plurality of flat conical columns are arranged on the surface of a substrate; and the distances between the flat conical columns are equal. The manufacturing method comprises the following steps of 1) adopting an epoxy resin glass fiber plate with Rockwell hardness of greater than or equal to 115 to manufacture the substrate, performing blind cutting on the substrate based on matrix points, and forming the flat conical columns which can satisfy printing and air guiding requirements of a printed circuit board from the residual part so as to obtain an air guiding plate; 2) enabling multiple pieces of epoxy glass fiber prepregs of the substrate to be matched with a release film, and performing high-temperature and high-pressure lamination in a vacuum condition; 3) after the whole substrate is cut, performing blind cutting on the substrate at fixed depth, and forming rectangular air guiding supporting points through blind cutting; and 4) processing the cylinder which is already formed through blind cutting into the flat cones with a small top and a large bottom. The processing method is simple and efficient and high in rate of finished products; the air guiding plate is very convenient to use, and the plate can be well supported; and the air guiding plate is formed in the mode of selecting the blind cutting supporting point.

Description

technical field [0001] The invention belongs to a production auxiliary tool for electronic products, in particular to a solder-resisting plug hole air guide plate and a manufacturing method thereof. Background technique [0002] In view of the continuous rise in the price of sheet metal, the production cost of the air guide plate used for the solder plug hole is simultaneously high (sheet material, drilling cost) and the production process is time-consuming, and the company’s overall operating cost is simultaneously increasing. Therefore, in order to optimize the air guide plate In order to reduce costs and improve efficiency, it is necessary to develop an economical, applicable, and reusable air guide plate. Contents of the invention [0003] Aiming at the above defects of the prior art, the present invention provides a solder-resisting plug hole gas guide plate with convenient and simple operation, stable quality of processed products, and low cost. [0004] A solder-re...
